Edsholms Castle, Medieval castle ruins in Grums, Sweden.

Edsholms Castle is a set of stone ruins standing on elevated ground near Slottsbrosundet, overlooking waterways that connect to Lake Värmeln. The site displays the structural layout of a medieval Swedish fortification with visible foundations and remaining wall sections.

Edsholm was probably built in the 1370s by Marshal Erik Kettilsson Puke at a strategic point controlling the water route toward Lake Värmeln and the inland road from the west coast through Dalsland to Bergslagen. It served as the seat of the king's bailiff in Värmland. Its last commander, the knight Herman Gisler, saw it taken and destroyed in 1434 by Värmland peasants under Peder Ulfsson (Roos) during the Engelbrekt Rebellion; it was never rebuilt.

Edsholm was one of Värmland's three medieval castles, alongside Saxholmens borg and Amneholm near Gullspång. It housed the king's bailiff, and the last commander was the knight Herman Gisler. Excavations in 1991–1992 produced reports on the household and on osteological finds from the site.

The ruins are accessible via marked paths in Grums Municipality, where informational panels explain details about the medieval structure. The elevated location provides good visibility across the site and surrounding landscape.

Edsholm was one of only three medieval castles in Värmland, alongside Saxholmens borg and Amneholm near Gullspång. The 1991–92 excavations produced reports, including an osteological study of animal bones by B. Hårding and E. Svensson's account of daily life in the bailiff's castle.
